FIELD: electrical engineering.SUBSTANCE: during implementation of the proposed method for manufacture of magnetic circuits for axial electric machines coiled cold-rolled electric steel, in the process of pulling motion, is simultaneously cut into specific number of strips of specific width and quantity; prior to assembly, one cuts slots in the strip[s and performs annealing; then each strip is wound onto an individual inner ferromagnetic ring of specific diameter with subsequent on-pressing of a corresponding number of external ferromagnetic rings of corresponding diameters onto a steel package of specific external diameter. According to this invention, straps of specific length made of a diamagnetic material are fixed at specific distances from the beginning of the electric steel strip between the coils thereof, the straps forming coaxial cylindrical surfaces and ensuring mutual magnetic insulation of axial magnetic circuit modules thus produced; the length of the diamagnetic material strips and the radius of the produced coaxial cylindrical surfaces are calculated so that to ensure equal area of butt-end parts of the axial magnetic circuit modules.EFFECT: ensuing uniform magnetic saturation of magnetic circuits, more efficient usage of magnetic material, enhancement of energy and weight and dimension indices of axial electric machines.2 dwg |
